Doppler ultrasound images of the distal vessels in the left kidney (top) and in the right RA (in the middle) acquired for the same patient as the CT data shown in Fig. 2. Bottom: reconstruction of the mean velocity profile in the right RA from the DUS data within one cardiac cycle (blue line). The red horizontal line indicates the calculated velocity value averaged over the cycle duration
